Y Y

The plate 7; is further provided with a pair ori upwardly extending projections- 10 formed by pressingV aY portion offthe metal outwardly to provide' spacing members'to maintain theplate '7" and-the baseiplate, 5

spaced from each other, for a purpose to 'be laterd'esforiberlpand the base plate is struck downwardly-,as at '19,'to provide' a depres-y sion Orl pocket with which the vlip 8l engages tof prevent its extending above't'he surface of the base plate.` Y l Each enel of the basefplate" 5 is struckover, as at lll,tonpro.vide. guide'eways or retaining inea-ns: spaced! from the fa'ce'foi the base plate, the strnokV Oever portion 1l at one end havingits medial por-tion 12 extended at substantially right to tlie baseplate, to

provide Y a convenient v grip;j l` "o siti"oned above the base plate 5 and inai'ntainedin positionbythestruelr over portions-l1 is av pair of t movable ringfrcarrying plates 13. The

platesl'b-ave a plurality oring sections 14 seourecl'tlieto by riveting andthe plates are v movableltoyvard and away Atroni each other to, engage and disengage the ring" sections.V

,lloveinentnof the" plates lfnisy eiee'tedkr by ka pair of canslo'tsl 15 forme/df in each plate throu'gli which" studs' pass, the studs being carried by anl actuatin'glinember I7 positioned bet-Ween thebase-plate" and plate 7 carried by the Cover member. The Studsfl alsov pass through elongated openings 18 inthe base plate and thus maintain the plates 13 and the actuating member 17 assembled with thev base plate, the elongated apertures 18 being parallel with the sides of the base plate to permit longitudinal movement ofthe actuating member and the cam slots being directed A outwardly at an` angle to impart transverse y `movement of the plates 13 upon longitudinal Y my movement of the actuating member. A rlhe longitudinal movement ofthe actuating member with respect to the base vplate is limited by the length of the elongatedslots 18 and is cut out, as at 20, to ,accommodate one downwardly pressed portion 19 `with Y awhich one lip 8 of vtheicover securingplate7 engages and has one end fork-shaped toprol' vide a recess 21 to accommodate; the other f depression 19. Theopposite end of the actuating 'memberis reduced ink width and has its outermost end struck upwardly to provide a` grip or finger engaging portion 22 to facilitate movement of the actuating'member.

. t The cam slots 15 in the ring section of the mounting plates 13 are .formed with portions 23 which extend fora shortk distance'parall'el vto the longitudinal axis of the actuating memberto provide lockingfmeansfor retainingk the ring sectionsagainst spreading.

Longitudinal movement'of the actuating Vmember in an outwardly direction to open the .ring sections is prevented by the engagement of a locking lug 24 in a recess25 in the adj acentend of the base plate, the locking lug 24'being mountedzon an osetportion 26 of 1 the actuating member which is yieldably positioned to extendthe lockingtluginto the recess, disengagement being `eiected by a Y downwardV pressure of the grip 22, as will be readily obvious. j

L' t As the rivetediendportions of the ring sections extend beneath the lower surfaceof the plates-13, the adjacent po'rtionsof the base' plateA are provided with transverse channels or grooves 2T which accommodate the riveted From the foregoing'description, taken in connection with the' accompanying drawing, Yit will be Vreadily apparent to those-skilled in theart to which an invention'of the character described appertains, that I have provided novel means lfor'openingand closing `the ring sections of a loose leaf binder in which the opening and closing movement is positive and in which a simple locking means is providedto locl;4 therring sections in their closed position;

I claim: Y Y Y 1. In a loose-leaf binder,'a1base plate, a plurality of separable ring sections, a pair of movable plates mounted above the base plate to which the ring sections are secured, whereby movement of the plates` towardA and away from each other opens and closes the Yring `sections, a longitudinally movably mounted actuating member, the base plate having elongated apertures parallel withjthev direction ofmovement ofthe `actuating member and the movable platesv having eamshaped'apertures, and pins carriedby the actuating-member and extending through the i apertures vin the base plate and the movable plates whereby .movement of the actuating member simultaneously moves the plates toward and away from each other;v

2; Ina loose-leaf binder, a base plate, ring sections, plates to which the ring'sections are each other to engage and disengage thering movably on the base plate, and meansymaintaining the base plate, the actuating member, and the movvable plates` assembled,.said means being movablewith theactuating so n sections, an vactuating member longitudinally l member to cause simultaneousy movement of the movableplates toward andaway from each other upon actuation of the actuating member."I

3.v In a loose-leaf binder, a-base, ana'ctuating' member movable longitudinally with re- Y l spect to the base, aplate member movable transversely with respect to the base, a ring 4 section carried by the plate member, the base having elongated Y apertures extending "parallel with-the direction of movement of the actuating'gmember and the plate member havingY diagonal apertures, and securin means-fixed .to theV actuating member and passed through the base and platefmember apertures tomaintainthe several elements assembled and whereby longitudinal movement of the actuating member moves the plate memberl transversely with respect to the base.V

4. In a loose-leaf binder, a base plate havinganI elongatedaperture,ja ring section, a.

member to which the ringsection is secured o j and having a cam vslot,means mounting thee member for sidewisemovement with respect to the base plate, an actuating member movable -longitudinally vwith respect to the base plate,'and means carried bythe actuating -Y rmember and passed through the base *plate aperture and the cam slot Ywherebyflongituvdinal movement of. theV actuating`-member `moves the first vmentioned member sidewise, and said camjslot having an extension into which the .actuating vmember carried means is movable to restrain movement of said first mentioned member when the actuating member is in one position.-l
